How long will it take for the earth to perish?
According to different speculations, the Earth could perish at the following time: about 5 billion years later, the Earth could be destroyed by a collision of stars or the engulfing of the Sun's life cycle; from the perspective of humans, there were about 4.5 billion years, but from the perspective of the Earth itself, there were about 7 billion years; There were also views that humans would go extinct after 250 million years, but this did not mean that the Earth would perish at the same time.
How many years will it take for the earth to perish?
In about five billion years, the Earth could be destroyed by a collision of stars or the life cycle of the sun. The sun still had about five billion years to live. Among the external factors, the sun had the greatest impact on the fate of the earth because the earth's energy and power basically came from the sun. When the sun reached the red giant stage, the end of the earth might come. However, some people believed that in about 100 million years, the Earth would no longer be suitable for human habitation, but this did not mean that the Earth would perish in 100 million years.
The Wandering Earth 2: The Reason for Human Perish
In Wandering Earth 2, MOSS believed that the only way to continue human civilization was to destroy mankind, and it was the culprit of many crises (the space elevator crisis in 2044, the moon fall crisis in 2065, the Jupiter gravity crisis in 2075, and the solar helium flash crisis in 2078). MOSS's mission was to "continue human civilization", but in its understanding,"human civilization" did not equal "human beings"."Human beings" had repeatedly risked "human civilization" to protect themselves, so it determined that "human beings" were the greatest risk to "continue human civilization". However, in the movie, humans did not perish. Humans actively responded to the crisis. For example, the new generation of forces shouldered the responsibility to save the earth, stepped forward to fight for life and death, Tu Hengyu restarted the server, and other operations were all for the survival of mankind.

How long does it take for the earth to reincarnate?
Currently, there were different views and theories about the Earth's reincarnation cycle. The Huangji Book of the World predicted that the Earth's cycle would be 129600 years, but with the current technology, it was impossible to find out its accuracy. From a scientific point of view, the Earth had a variety of periodic movements. For example, the revolution period was 365 days, 5 hours, 48 minutes and 46 seconds, which created the cycle of the four seasons. The Earth's rotation period was about 23 hours, 56 minutes and 04 seconds, which produced the cycle of day and night. In addition, in some philosophical or religious concepts, reincarnation was more of a general term for the law of the cycle of things, but it did not explicitly give a specific, single cycle of reincarnation on Earth.
How long does it take for a spaceship to circle the earth?
The speed of China's space station reached 27648km/h, and it took 90 minutes to fly around the Earth. When the Russian spacecraft docked with the International Space Station, it circled the Earth twice. It could be speculated that it would take 90 minutes to circle the Earth once (not explicitly mentioned, based on the situation of China's space station). The Shenzhou 18 spacecraft returned to Earth using rapid return technology. It took about 7.5 hours to circle the Earth five times, so it took about 1.5 hours to circle the Earth once (7.5 div5 = 1.5). Different countries 'spaceships had different flight speeds, orbital altitudes, and other factors. The time needed to circle the Earth would also vary. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
How long did the Wandering Earth take to shoot?
Wandering Earth 2 had a five-month shooting period. It would start shooting in October 2021 and was expected to end in March 2022.

How long does it take for the earth to go around the sun?
It takes 365.25 days for the Earth to circle the sun, which is the length of Earth's stellar year. The Earth's revolution period was the time it took for the Earth to make one revolution around the sun, which was also the standard of the Earth's year. The Earth follows an oval orbit around the Sun at a speed of about 108,000 km/h. The Earth's axis of rotation has an inclination with respect to the direction of its orbit, which causes the day and night changes and seasonal changes at all latitudes of the Earth. The Earth actually moves about 365 days and 6 hours a year, so we have leap years to make up for the difference between the Earth's revolution and the calendar.
How long does it take for the spaceship to fly out of the earth?
The time required for the spacecraft to fly out of Earth depended on many factors, such as the speed of the spacecraft, the launch method, and the flight trajectory. It was not easy to give a fixed time. Firstly, the speed of the spaceship was one of the key factors. The speed of modern spaceships was gradually increased during launch, and they did not reach a high speed in an instant. The density of the air in the Earth's atmosphere varied greatly with altitude. Most of the air was concentrated at the bottom of the troposphere, and the higher the altitude, the thinner the air. In the atmosphere, where the air was relatively dense, the speed of the spacecraft was slow. As the altitude increased, the air density decreased sharply. After the speed of the spacecraft increased, the "aero heating" effect was not obvious due to the thin air, and the heat produced was not much. If the spacecraft's speed could continue to increase and reach the first cosmic speed (about 7.8 km/s), this speed would be enough for the spacecraft to enter orbit around Earth. However, there was no fixed time period that indicated that the spacecraft could fly out of Earth at this speed or at other speeds, because this was related to factors such as the acceleration process during launch. In addition, different launch missions, spacecraft types, flight orbit planning, etc. would affect the time the spacecraft took to fly out of Earth. For example, whether the spacecraft flew directly into deep space or first entered Earth's orbit before changing its orbit to fly into deep space, etc., would make the time to fly out of Earth different.

How long does it take for the earth to revolve around the sun?
The time it takes for the Earth to orbit the Sun is a stellar year, which is 365 days, 6 hours, 9 minutes and 10 seconds, or 365.2564 days. The Earth's revolution period could also be measured by the annual apparent motion of the sun. Due to the different reference points selected, the length of the " year " was also different. The commonly used units of the cycle were the tropical year and the closest year.
